I've never had it happen with my collection, but never say never! About a year ago, I recall reading about someone in Canada having a T. ionantha mother plant bloom twice (blooms were about 6 months apart). No pictures were provided, so I took it with a grain of salt, per se.

I have seen a few of my ionanthas start to re-blush after flowering and producing pups. The mother slowly reverted back to a green color after flowering, and then flushed with a less intense pinkish/red coloration near the uppermost top of the plant sometime later.

Thank you for the info. I figured it was kind of rare. Ill see if I can dig up more pictures of the first bloom to prove its the same plant. A second flower emerged today.

It happens frequently with T. ionantha and it's cultivars. Your plant is ionantha var. stricta forma fastigiata.
